Munich/Essen, 1 July 2025 – Munich-based ClimateTech startup Otter Energy Trading has successfully completed a pre-seed financing round. Investors include the GF BRYCK Ventures fund and experienced business angels. Otter Energy Trading plans to use the fresh capital to further develop its automated platform for local electricity trading and accelerate its market launch.
The startup enables operators of photovoltaic systems to market their self-generated electricity more efficiently: Through Otter Energy Trading, owners of PV systems can automatically sell their electricity locally to tenants, supraregionally to secondary locations and other companies, or on the stock exchange. Thanks to these trading options, Otter Energy Trading can market the electricity much more profitably than is currently possible through the EEG remuneration system.
“Germany has made excellent progress in decentralized power generation over the past few decades. Now, with decentralized and simple power trading, we are providing the missing piece of the puzzle for the energy transition, as power trading is currently far too complicated for end customers. In the future, even non-professionals will be able to participate in power trading through us,” says founder and CEO Niels Schubert. “With the support of GF BRYCK Ventures and our business angels, we can further develop our technology and give more companies access to profitable electricity trading.”
The young company is thus making previously complicated models such as energy sharing easy to implement – and enabling companies to use surplus PV electricity at other company locations, for example, which saves high electricity costs.
GF BRYCK Ventures is a €10 million fund newly established in April by the BRYCK start-up and innovation center and VC investor Gründerfonds Ruhr, financed by the RAG Foundation. The fund aims to provide targeted support to B2B tech and, in particular, deep tech start-ups in Germany that have successfully completed a BRYCK program.
“Otter Energy Trading addresses one of the key challenges of the energy transition—the efficient, decentralized marketing of renewable energy,” says Ann-Christin Kortenbrede, Managing Partner at GF BRYCK Ventures. “The team impresses with its technical depth, entrepreneurial clarity, and strong vision. We are delighted to accompany Otter on this journey,” adds Dr. Fabian Hogrebe, Investment Manager at GF BRYCK Ventures.
Otter Energy Trading was founded in 2024 and is based in Munich. The company focuses on developing software solutions for energy trading and offers services in the areas of direct marketing, PPAs, and storage control for PV systems.
